I've been researching these pills & injections on Google Scholar (scientific journals & articles). So far, I've been unable to unearth any evidence that they do what they claim to or that they're safe. So many companies are out there making extravagant claims about their bleaching pills or injectable formulas. Untill I see some serious scientific evidence, I wouldn't risk it. If I do find a UK source, I will forward it to you & you can investigate it & share your findings with the group. Good luck!
